Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed June 25, 1913. Serial No. 776,698.

To all whom it may concern: I

Be it known that I, HENRY WAYMOUTH FRANCE, consulting motor engineer, residing at London, England, have invented cerheard at the receiving end without the receiving instrument being held to the receivers ear. The invention thus obviates the necessity of remaining by the instrument when waiting for a message to be continued.

g It is carried out as follows :A sound: trumpet of suitable shape and size is placed in front on a platform or su port provided with guides disposed behin said trumpet. Said guides are adapted to support the telephone receiver in such a manner that when same is placed in position the ear piece presses against the small end of the sound trumpet; the diaphragm of the receiver being coincident with the orifice of the small end of the trumpet. The sound from the receiver is thus magnified and may be heard throughout a room of usual size. 7

In a modified form the sound trumpet is made approximately U shape, and the smaller end is provided with a horizontal tray shaped to correspond to the ear piece of the receiver, upon which the telephonereceiver is supported when the device is in use. At the termination of the conversation the receiver is lifted off the device and replaced upon the telephoneinstrument.

' The inventioh will now be described more particularly with reference to the accompanying drawingsin which Figure 1. is a 'side.view ofthe invention.

trumpet orifice. If, desired means ma provided for depressing the receiver Fig. 2. is a front view of one of the supporting guides, and Fig. 3. shows a modified form of the invention.

In the drawings, 1 is the sound trumpet made from, any suitable material, and attached to the platform or support. 2, by means of thevbrace 3' or otherwise. Behind said trumpet are mounted the guides 4 and 5. The guide 4 is made bow shaped as shown, while the guide 5 is slightly inclined. When inuse, the telephone receiver 6 is placed on the guide 4, when, on account of the inclined position ofguide 5, said receiver slides into positionagainst the trumpet 1, and with theear piece pressing against the small end 7 of the same.

In the modified form shown in Fig. 3, the trumpet 1 is made approximately U shaped, the small end 7 being provided with a horizontal tray 8 shaped to correspond to the ear piece of the receiver, adapted to support the receiver 6 in such a manner that thediaphragm of gsame is coincident with the e ook of the telephone when the invention is not in use. The two forms illustrated are given byway of example.

I claime- The combination, with a supporting base,

and a trumpet securedthereto and having its main portion arranged horizontally; of an inclined'guide secured tothe base plate to the rear of the inlet opening of the trumpet and adapted to press the rent end of a telephone receiver against the trumpet, a support secured to the base between :the trumpet and the guide, and a telephone receiver supported horizontally and held in linewith the inlet opening of the trumpet by the'said support and ide.
